FAQ
304 stainless steel flanges have higher carbon content, offering standard corrosion resistance and strength. 304L flanges, with lower carbon content, provide better weldability and reduced risk of intergranular corrosion, making them suitable for welding applications.
While both 304 and 316 stainless steel offer good corrosion resistance, 316 stainless steel contains molybdenum, which provides enhanced resistance to pitting and crevice corrosion, especially in chloride environments. 304 is generally more cost-effective and sufficient for many applications.
Yes, 304 stainless steel flanges have excellent weldability, making them easy to join with other pipes and fittings without compromising strength or corrosion resistance.
304 stainless steel flanges are low maintenance. Regular inspections and cleaning are typically sufficient to prevent any potential corrosion or buildup, especially in aggressive environments.
